I'm getting a noticable lag when navigating around standard folders in the filesystem. It's taking much longer than it should to load and display folder contents. I just set Nemo to default file manager and uninstalled Nautilus. I originally installed Linux Mint 14 Mate, but switched over to Cinnamon about a week ago - could that have anything to do with it? My machine is a Dell XPS 15 L502X.

I have the same issue. Just upgraded to Mint 14 (Nadia) from 13 (Maya); clear install, but I did have a separate home partition, which I retained. (I'm just mentioning this in case the slowness of Nemo could have something to do with the files manager using old Nautilus user data; it did, after all, remember my Nautilus bookmarks.)

Same thing happened to me...using mint 14 Cinnamon 32b. Tried completely uninstalling nautilus, but did not fix it.Anybody has some clue on how to fix this? It's really annoying cause there's a considerable lag when opening folders with even just 2-3 items .

I've been experiencing the same sluggishness on three of four boxes running Ubuntu Quantal (desktop/64) with Cinnamon/Nemo. The box that WASN'T exhibiting the sluggishness was subscribed to the STABLE PPA, but yesterday when I switched it to the NIGHTLY PPA it immediately began exhibiting the same sluggishness.

Another "feature" of the sluggishness is the (majorly-annoying) repetitive column auto-resizing... -- happens on all four boxes now -- makes me dizzy.

I haven't (yet) tried rolling back one of the boxes to the STABLE PPA to see if there's any change. I'll give that a go over the weekend though.

Haven't been able to undo whatever happened when I "upgraded" to the nightly PPA; even completely removing Cinnamon/Nemo and reinstalling from the stable PPA doesn't resolve the excruciating SLUG-ishness and etc. (???!!!)

Installed SpaceFM and it's supersonic compared to Nemo, so gonna take a guess the problem is in Nemo. (Both stable and nightly Cinnamon PPA.) Also gonna take a guess it has something to do with the column auto-resizing, which goes on and on and on and on and...

...and just for good measure, via Synaptic completely removed libnemo-extension1 and nemo-data.

Those two I had to mark for installation again before I was allowed, still from Synaptic, to mark Nemo for installation. (I guess removing libnemo-extension1 and nemo-data was pointless.) Also (re)installed nemo-dropbox.

The result? I do think Nemo is faster now than it was before. It's still not lightning-fast, though; takes a bit over 20 seconds to load a folder (as in: switch to that folder while Nemo is already running) that contains 440 image files that amount to a bit under 100 MB; and that's in list view and after I having had the folder open several times already (meaning the little thumbs should be cached). Given that I'm running Mint 14 Cinnamon on a machine with a relatively pedestrian 1.83GHz processor with 2 GB DDR Ram, that's perhaps all I can expect; it's something that I can live with. (Thunar is much faster, of course; but I do miss search capabilities.)

(I also have Mint 14 installed on a computer with 4 or 6 GB Ram and a faster processor (don't remember right now; the computer's at work), and there Nemo is quite fast -- on a fresh install, with no Mint 13 or anything relevant previously installed.)

One thing I might still try out. Even after deleting the Nautilus- and Nemo-folders in .config, Nemo (after being re-installed) still remembered my bookmarks, and loaded the files in an order it knew from before (= not strictly alphabetically; a bunch of files would load faster or earlier). I vaguely remember that Cinnamon somewhere stores user info it would use for any file manager, such as bookmarks. I wonder whether it would be worth a try locating where that info is stored, and erasing it as well.

On one machine I've switched back to Nautilus (3.4.2) for both FM and Desktop management (completely removed nemo) and it's clearly much faster. But, SpaceFM is still noticibly faster (as a file manager.)

The repetitive column auto-resizing in Nemo is excruciatingly annoying, AND it takes up a lot of time. I wish there was a way to disable it.

I'm experiencing the same slowness/lagging in Mint 14 Cinnamon.I posted in a forum elsewhere in Mint forums.I wouldn't mind removing Nemo but am afraid that I might break something in the process.It seems that

isnt' enough to really remove all of it.I've never had these problems in the past and I do a LOT of copy/paste over my network so I can install games.This Nemo slowness and even freezing makes it impossible to use.

Just a normal open folder action is much slower than one would expect, even for a folder with just 2 or 3 items.

I'm using mint 14-32b-Cinnamon on an iMac 8.1 (Core 2 Duo, 2.66 GHz, 4GB Ram) and on an Asus U36SG laptop (Core i5 Sandy Bridge, 2.5 GHz, 6GB Ram) and both machines show this behaviour...it started happening "just like that" when I started using mint 14 (previously I had been using mint 11 on both machines for quite some time and didn't have this problem: nautilus was really snappy; btw, mint 14 was a clean install in both cases).Have tried removing nautilus (though I've kept the nautilus-data package, since unistalling it would touch lot of packages and I was afraid to break the system); this didn't solve the problem, however.

Pls Help!!! This really is a crippling issue, it's darn slow to navigate the filesystem the way nemo is right now...

Thx a lot for paying attention to this issue, Thx even more if u can solve it!

All the best and keep up the good work you and the mint team have been doing until now (love the way Cinnamon is evolving!).

Using Linux Mint 14, I'm noting this behavior (extremely slow file operations) with Nemo, Nautilus and Caja. I've even had the experience that creating a new directory on a USB drive results in a "File operation" window with status bar opening -- something that should be nearly instantaneous. Also, I tried to transfer about 2 GB of files to a TrueCrypt directory and it completely hung the window manager -- the clock still operated but no windows were responsive.

Can you give me an example of when nemo is sluggish? For instance, can you install nautilus alongside it and describe a sequence of actions which are slower to perform in nemo than in nautilus?

In my case, I would copy a game folder from my Fedora 8 server with Samba and paste in Mint 14.The copy would start and then stop at random % and never finish.I would wait and wait and wait... nothing.But copying it again would result in a warning saying there is already and operation in process.So I would have to:

Clean new installation of mint cinnamon keeping only home partition intact solved the problem with Nemo for me. The problem I had with the Cinnamon menu being also slow was completely unrelated and solved it by changing settings in Cairo dock (taskbar behavior -> none).

Nothing's happened on this? I mainly use Thunar now, though I do miss Nemo's search capabilities; but loading any folder in Nemo still takes a really long time. CPU usage goes up pretty high as Nemo is loading, reaches percentages in the nineties on my admittedly no longer state-of-the-art computer. (Processor: 2x Intel Core2 Duo T5550 @ 1.83GHz, Memory: 2GB)

I'm still wondering whether this might have something to so with what I had installed previously. I'm running Mint 14, from fresh install, but retained my /home partition; had run Mint 13 before, with Nautilus as the default file manager.
